DBI-Sala 3400169 Sealed-Blok Self-Retracting Lifeline 85 ft Stainless Steel Cable SRL

The DBI-Sala 3400169 Sealed-Blok Self-Retracting Lifeline (SRL) is a premium fall protection device engineered for use in the most demanding industrial environments. Featuring 85 feet of stainless steel cable and a 420 lb capacity, this OSHA-compliant SRL is built to protect workers at height across a wide range of industries. It replaces and supersedes formerly sold SKUs 3400862 and 3504485.

At the heart of this SRL is a patented sealed-component design that physically isolates all dynamic internal components — including the motor spring and brake — from grease, moisture, and dirt. This means consistent, reliable performance regardless of how contaminated or wet the surrounding environment becomes. An additional patent-pending feature reduces retraction speed, minimizing stress on the SRL and adjacent equipment when the lifeline is released.

Key Features:

• IP-69K Rated: Protects against dust ingress, high-temperature exposure, and high-pressure water jets for extreme-environment use
• 85 ft (25 m) Stainless Steel Cable: Corrosion-resistant lifeline suitable for washdown, chemical, and marine-adjacent environments
• 420 lb Capacity: Supports OSHA-standard worker weight requirements
• Patented Sealed-Blok Technology: Separates motor spring and brake from foreign elements including grease, moisture, and dirt
• Reduced Retraction Speed: Patent-pending technology limits forces on the SRL and surrounding equipment upon release
• Swiveling Self-Locking Snap Hook: Equipped with an impact indicator for post-fall inspection
• Centrifugal Energy Absorption System: Activates automatically during a fall event to arrest descent and reduce forces on the user
• OSHA Compliant: Meets applicable OSHA fall protection standards

The Sealed-Blok SRL extends as the user moves away from the anchor point and retracts automatically, allowing normal movement within the working area. Should a fall occur, the internal braking system engages instantly to stop the fall. This unit is particularly well-suited for confined space entry and retrieval operations, and is available in SRL, Retrieval SRL, and RSQ/Rescue configurations. Formerly sold as SKU 3400862.
